BATTERY PLUG.

Application am much as, 1923. Serial a... cameo.

To all whom it may concern:

Be it known that I, WILLIAM H; ELLIs, a citizen of the United States,and'resident of Two Rivers, in the county of Manitowoc and State ofWisconsin, have invented certain new and useful Improvements in BatteryPlugs; and I do hereby declare thatfthe following is a full, clear,-andexact description thereof. i

This invention relates to plugs and is particularly directed to'a fusedplug.

Objects of this invention are to provide a conductor receiving plu whichis fused and which may be readily inserted within a standard socket,which is compact in design, which is so constructed that the fuse may bereadily renewed, and which is so constructed that it may be used toadapt a standard screw plug to a fused plug.

An embodiment of the invention is shown in the accompanying drawings, inwhich- Figure 1 is a side elevation of the plug with aportion brokenaway to show theinterior construction.

Figure 2 is a longitudinal, sectional view of the auxiliary plug, suchview corresponding to a section on the line 2-2 of Figure 45.

Figure 3 is a corresponding, sectional view on the line 3--3' of Figure4.,

Figure 4 is an end view of the auxiliary v plug.

The auxiliary plug is adapted to be inter with a central contact 6,electrically connected with socket members 7 and 8 respectively. a

The auxiliary plug comprises an insulating body 9, preferably ofcylindrical contour and provided with recesses within which arepositioned the sockets wand 11 adapted to receive the projectingcontacts 2. These sockets are provided with terminal portions equippedwith attaching'screws 12 and 13. They open towards a pair of slots 14through which-the projecting contacts of theauxiliary plug .9 isprovided with pro ecting contacts 15 and 16-equipped with base portionswhich carry screws 17 and 18. Conductor 19 electrically joins thecontact 16 and thesocket 11 and is held in place by means of the screws,Band 18. A. fuse 20 electrically connects the contact 15 with the socket10, as may be seen from- Figure 4 and is removably held in place bymeans of the screws 12 and 17. "Obviously, the conductor 19 may be afuse, if desired-but it is preferable to provide the fuse, asindicatedat 20and as just described.

The other face I It will be seen that thisauxiliary plug I may receive the projecting contacts 2 in the sockets 10and 11 and that the member 4 may thenbe positioned',its sockets 7 and 8receivingthe projecting contacts 15 and 16 of the auxiliary plug.In'this. manner the standard type of screw plug is adapted or altered bymeans of the auxiliary plug, so as to constitute a fused plug.

It will further be seen priated elements of the composite plug andsubstituting a new fuse. p

, It is intended that. this auxiliary plug shall be supplied where it isdesired to adapt a standard plug to the fuse plug type. However, it isobvious that if these plugs were manufactured" as an entity, it might bedesirable to form the members 1 and 9' as a single unit and it isintended that this invention shall include such construction.
